46 guns on the Prinses Louise in late 1652

I have been studying the Van de Velde drawing of the Prinses Louise to see how she might have been upgunned to 46 guns. The ship seems to have had 20 guns on the lower tier (4-24pdr and 16-12pdr), 4-12pdr under the forecastle, and 10-12pdr under the quarterdeck. There were also 4-5pdr on the quarterdeck. I am not sure what size guns were used, but there was room to arm the waist with 6 guns and add 4 guns forward on the quarterdeck. Unless temporary sides were added, they probably were unprotected except for "arming cloths". Sources:
